Comment 5 for bug 1334495

Thanks for the additional information. It indicates that qt based applications don't play well with fontconfig.

However:

Which font settings are those? Is it possibly something KDE specific that overrides fontconfig for KDE apps? If so, is there possibly a way to change them to 'neutral' values?

In 14.04 the default font for rendering Chinese was changed from WenQuanYi Zen Hei to Droid Sans. This might have something to do with it.

It's still not clear to me which packages are affected, but I added a few candidates so this bug report gets more attention.
